Be it known that 1, HERBERT A. BOWEN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Refrigerator-Cars, ofwhich the following is a specification, reference being had. to theaccompanying drawings, in Which- Figure 1 is a vertical cross section ofa car showing one end thereof. Fig. 2 is a horizontal sectionon line 2-2of Fig. 5. Fig. 3 is a plan view of one of the supporting frames. Fig. 4is a section on line 4--4 of Fig. 3. Fig. 5 is a partial longitudinalvertical section of a car; and Fig. 5 is a partial sectional view of oneof the tanks, on line 6-6 of Fig. 2.

My invention relates to refrigerator cars,

and has particularly to do with the devices for holding the coolingmixture employed for maintaining the car at the proper temperature.

My invention consists in the novel features and the combination andarrangement of parts hereinafter fully described and afterwarddefinitely pointed out in the claims.

In the drawings,-7 indicates the door of a car, 8 its roof, and 9--10its sides.

. 11 indicates the foot-board.

12 indicates the ceiling', and 13 one end of the' car.

leindicates tanks which are adapted to co n- The tanks 11 are preferablycircular, or substantially so, in cross section, except at their upperends, where they are squared, as best shown in Figs. 1 and 5. Each tankwlet is provided with an internal passage or tube 15, the upper end ofwhich opens into the car, its lower end extending through the bottom ofthe tank, so that a longitudinal passage is provided through the tank,as indicated by dotted lines in Fig. 5. The tube 15 is preferablyconical in form, as shown in Fig. 6.

The tanks 14c are arranged across the ends of the car, as shown in Fig.2, and are preferably four in number. They are supported upon frames 16which are shaped to correspond with the bottom of the tanks, and areprovided with lugs 17 at suitable points to prevent the tanks frombecoming displaced.

Atdiametricallyopposite points the frames 16 are provided with trunnions1S-19, as shown in Fig. 3. A central opening 2O is also provided in eachframe, which openings align with the tubes 15, as shown in Fig. 6. Theframes 16 are adapted to be supported by bars 21-22, a pair of barsbeing provided for each frame, as shown in Fig. 2. Each pair of bars21-22 is connected at the rear by a rod 23. Their rear ends aresupported by brackets 24 projecting from the wall of the car, as shownin Fig. 2. The forward ends of the bars 21-22 is supported by rods 25which are secured to the roof of the car, as shown in Fig. 5, and passthrough suitable slots in the forward ends of the bars 21-22, where theyare secured by nuts 26, as shown in Fig 5.

By unscrewing the nuts 26 the forward ends of the bars 21-22 may belowered, th-e bars swinging upon their brackets 24 as pivots. Atsuitable points the bars 21-22 are provided with bearings which receivethe trunnions 18-19. The brackets 24: and rods 25 are so adj usted thatthe frames 16 will be held several inches above the loor of the car sothat air may freely circulate under the tanks.

The upper ends of the tanks lat are secured to prevent them from rockingby frames 27 which are of such size as to tit tightly into the upperends of the tanks, as shown. in Fig. 5. In order to secure a better iitthe sides of the frames 27 are inwardly inclined so that they may bewedged tightly into the upper ends of the tanks 14. The frames 27 aresecured to the inner casings 28 of the car hatchways by screws, or inany other suitable manner.

29 indicates a pan located beneath the tanks and extending across theend of the car, which pan serves to receive any drippings from thetanks, whence they are carried off bya Waste pipe 30 extending throughthe bottom of the.

car and communicating with the pan 29, as shown in Fig. 5.

As shown in Figs. 1 and 2, the lower portions of the tanks 14communicate with each other through a series of pipes 31-32 which arecoupled by a flexible coupling 33, so that the depth of Water in thevarious tanks will be equal and the water from all the tanks may bedrawn oft' through a single discharge IOO pipe extending from one of thetanks. By thus flexibly connecting the several tanks they are notinjuriously aected by the jarring of the car and they may be more easilyconnected up after having been put in place.

In order to inclose the tanks and prevent them from being damaged byarticles in the car, doors Sit-35 are provided, Which are hinged byhinges 36 to the sides of the car, as shown in Fig. 2.

37 indicates a stop for the meeting edges of the doors Set-35, whichstop is formed by a bar 38 which is secured to the end of the car on themiddle line and extends forward between the tanks to the proper positionto receive the inner edges of the doors 34e-35.

7vVhen it is desired to remove one of the tanks, the doors 34-35 areopened and the rods 25 are released from their connection With the bars21-22, permitting such bars to drop, thereby moving the upper end of thetank out of engagement with the frame 27 so that it may be tiltedforward on its frame 16 and removed. It Will be seen therefore that bythe improvements described the Work of removing or replacing the tanksis simplified to the greatest degree.

I do not Wish to limit myself to the specific details of constructionherein described, as, so far as I am aware, no refrigerator car hasheretofore been constructed having removable tanks.

That which I claim as my invention, and desire to secure by LettersPatent, is

1. The combination with a refrigerator car, of a vertically movable tankand a Wedge shaped open frame adapted to fit into the upper end ofI saidtank and communicating with a hatchway in the roof of the car,substantially as described.

2. The combination with a refrigerator car, and one or more tanks, of avertically movable supporting device for said tank or tanks, and meansfor securing the upper ends of said tank or tanks in position,substantially as described.

3. The combination with a refrigerator car, and a tank, of a frameadapted to fit into the upper end of said tank, and a vertically movablesupport for said tank, substantially as described.

4. The combination With a refrigerator car, and a tank, of a frameadapted to t into the upper end of said tank, and a pivoted support forsaid tank, substantially as described.

5. The combination with a refrigerator car, and a tank, of a frameadapted to fit into the upper end of said tank, and a vertically movablepivoted support for said tank, substantially as described.

6. The combination with a refrigerator car, of a tank, a pivoted supporttherefor, and means for securing the upper end of said tank in position,substantially as described.

7. The combination with a refrigerator car, of a tank, a verticallymovable pivoted support therefor, and means for securing the upper endof said tank in position, substantially as described.

8. The combination with side bars, and a frame supported thereby, of atank, and rods 25 adapted to be secured to the forward ends of saidbars, substantially as described.

9. The combination with bars 2l22, and brackets 24, of a frame 16, atank, and rods 25 secured to the free ends of said bars 21-22,substantially as described.

10. The combination with side bars, and a frame supported thereby, of atank, rods 25 adapted to be secured to the forward ends of said bars,and an internal frame 27, substantially as described.

11. The combination with a refrigerator car, of a series of tanksprovided at their adjacent sides near the front and bottom withoppositely projecting pipes, and flexible connections uniting theadjacent pipe, substantially as described.
